Performance of IntelliPrompt.InfoTip.Show(...)

In v4.0 we have code to automate the determination of what parameter is selected and have a new method ParameterChanged which tells you when the caret moves to a different parameter.

But in v3.1 what you essentially would do is in OnSelectionChanged, determine the parameter index that the caret is in. If it is different than before, update the data in IntelliPrompt.InfoTip.Info[IntelliPrompt.InfoTip.SelectedIndex] only. Then call IntelliPrompt.InfoTip.MeasureAndResize. I believe all those items are available to you in v3.1 and is what we essentially do in our implementation v4.0. That way you are only updating one item and it works fast.

thanks for your response.
I repace Show with MeasureAndResize, and it works well.

Hi,

I had this same problem and I've now switched to using MeasureAndResize.

However, whenever I perform a MeasureAndResize, the border of the InfoTip is always the same size it was originally so if the InfoTip is bigger than the previous one, the border is cutoff.

I noticed in the documentation that it indicates DesktopBounds should be used to get the new size after using MeasureAndResize but it doesn't say what I should do with the desktop bounds value.

Am I doing something wrong here?

Hi Karl,

Hmm... in the parameter info tips we use in the C# add-on, I'm not seeing the border issue occur. Could you send over code that can be added to the sample project to duplicate it? It should work appropriately based on what you are doing.

Hi,

Here's some code you can try. To illustrate the problem. Note that I'm not using any of the addons. This is just a standard editor.

To get it working, just type an opening bracket, "(" to activate the infotip. Then press any key to fire the code in the selectionchanged event.

Thanks,

Karl

            SyntaxEditor1.IntelliPrompt.ParameterInfo.Info.Add("Here is a test infotip.  Now press any key.")
            SyntaxEditor1.IntelliPrompt.ParameterInfo.Show(SyntaxEditor1.SelectedView.Selection.EndOffset)
        End If

    End Sub

        If SyntaxEditor1.IntelliPrompt.ParameterInfo.Visible Then
            SyntaxEditor1.IntelliPrompt.ParameterInfo.Info.Clear()
            SyntaxEditor1.IntelliPrompt.ParameterInfo.Info.Insert(0, "This is a longer infotip to show how the border doesn't resize.")
            SyntaxEditor1.IntelliPrompt.ParameterInfo.MeasureAndResize(SyntaxEditor1.IntelliPrompt.ParameterInfo.DesktopBounds.Location)
        End If

    End Sub

Thanks, we added a repaint call at the end of MeasureAndResize to fix this.

Great.

By the way the same problem occurs in v4.0 - I'm sure you already knew that though.

The latest build of this product (v24.1.1) was released 4 months ago, which was after the last post in this thread.
